The Fairly OddParents - 5x16a - The Good Old Days

Timmy's grandfather and Mr. Turner's father, Pappy, is coming over to babysit Timmy. Although Timmy is relieved that he doesn't have to spend time with Vicky instead, he is still frustrated when he learns that Pappy hates everything modern and refuses to partake in fun activities with Timmy. Only after he catches Timmy watching Captain Green and the Eco-Teens does Pappy share a common interest with Timmy: cartoons. To have a fun time with his grandfather, Timmy wishes that they were in a cartoon from Pappy's era, and the world of Dimmsdale becomes like a black-and-white silent film cartoon!
